Thanks Ryan,

I tried the fix but it just gave a different symptom.  (same error, 
different variable)
So... rpm --erase xen JIC there were any ghosts around.  Manually 
removed all traces of xen from the system.  Then did a ./install.sh from 
 the xen-3.0.2-2 directory, which had a clean "make world".
The results are the same.

I've found a more generic error about a local variable being used before 
assignment, but I think it's referring to dev_config.
Again, this only happens on auto-boot or domU reboot, and only when 
there is a "pci =" line in the domU's definition file.
Any ideas how I can help debug this?
